Polaris RPG

Polaris takes place centuries after wars and climate catastrophe rendered Earth's surface uninhabitable. Humanity sought refuge beneath the swollen oceans, guided by mysterious benefactors known as the Geneticians.

Theme and Setting

Now survivors cling to existence in underwater settlements called Havens, struggling with genetic degeneration, perpetual faction wars, and monsters of the deep. The world combines sleek underwater aesthetics with brutal survival stakes—society teeters between rebuilding civilization and collapsing into barbarism.

How Play Feels

The system uses a d6 dice pool mechanic where players roll attribute dice plus skill dice, counting successes. Combat is tactical without being overwhelming, with hit locations, armor values, and weapon variety.

What Makes It Distinct

Character creation offers four genetic types: normal Humans, Natural Hybrids, Geno-Hybrids, and Techno-Hybrids—each with distinct underwater survival capabilities. The game emphasizes resource scarcity, equipment condition, and the constant threat of drowning or pressure failure.

Where It May Not Fit

You mainly want short standalone sessions with minimal carryover You want a cleaner, less pressured world state.
